Apple Devices, Memory Corruption, CVE-2025-24190 (Critical)

How the CVE Works:

CVE-2025-24190 is a memory corruption vulnerability affecting Apple’s video file processing in multiple OS versions (visionOS, macOS, tvOS, iOS, iPadOS). Attackers craft malicious video files that exploit improper memory handling during decoding, leading to app crashes or memory corruption. The flaw allows arbitrary code execution or denial of service by manipulating heap/stack memory structures. Apple patched it via improved bounds checks and sanitization in media frameworks.

DailyCVE Form:

Platform: Apple OS Ecosystem
Version: visionOS <2.4, macOS What Undercode Say:

Exploitation:

Craft malicious video (e.g., H.264) with malformed NAL units:
```
ffmpeg -i payload.bin -c:v libx264 -crf 0 exploit.mp4
```
Trigger parsing via apps like QuickTime or Safari.

Detection:

strings suspect.mp4 | grep -E 'avcC|moov' Check for abnormal headers

Mitigation:

1. Patch immediately:

softwareupdate --list Verify updates

2. Disable auto-play for media:

<key>AutoPlayEnabled</key>
<false/> macOS plist

Debugging:

Use `lldb` to trace crashes:

lldb --attach-name QuickTime -- -malicious.mp4

Network Protection:

Block suspicious media MIME types:

location ~ .(mp4|mov)$ {
deny all; Nginx rule
}

Forensics:

Extract corrupted memory dumps:

sudo dtrace -n 'syscall::write:entry /pid == $target/ { printf("PID %d wrote %d bytes", pid, arg2); }' -p <PID>
